kernel: Wsign-compare warning fix by casting the result of a substration of pointers to an unsigned.

[Michael Stefaniuc]

Changing talloced to a signed integer isn't an option because it is
compared also to a DWORD parameter of FormatMessage() (an official Win32
function). Also the casts aren't that ugly as they are hidden inside a
macro.
This small patch fixes 27 -Wsign-compare warnings.
